US States Favor Clean Energy Siting Reforms Despite Surge In Restrictive Bills During 2026—Report

The debate over clean energy siting and permitting became one of the most significant energy policy issues across the United States during the 2026 legislative year. Rising electricity demand, rapid expansion of data centers, and the need to build new power infrastructure pushed state lawmakers to consider a wide range of proposals affecting renewable energy projects. According to The State of Siting: 2026 Legislative Round-Up released by the non-partisan Siting Solutions Project, although many restrictive bills were introduced, the laws ultimately passed by state legislatures largely supported the continued development of clean energy.

The report tracked 201 siting-related bills introduced across 40 states during the 2026 legislative sessions. Around 43 percent of these proposals aimed to restrict renewable energy development. These measures mainly focused on giving local governments greater authority over project approvals, increasing setback requirements, introducing stricter decommissioning rules, and imposing temporary moratoriums on new renewable energy projects. Most of these restrictive proposals emerged in southern states, areas experiencing rapid renewable energy growth, and states that already have established statewide siting frameworks.

At the same time, approximately 36 percent of the introduced bills took a more supportive approach toward clean energy. These proposals sought to simplify permitting processes, provide tax incentives for renewable energy investments, and encourage projects on brownfield sites or agricultural land. Battery energy storage systems received particularly favorable attention, with many states updating fire safety and operational standards to support the growing deployment of battery storage technology.

Despite the large number of restrictive proposals, the report found that most of them failed to become law. Industry groups, renewable energy advocates, and local supporters successfully opposed several high-profile measures that could have significantly slowed clean energy development. Proposed solar moratoriums in Alabama and Missouri, legislation that would have effectively limited renewable energy growth in Arizona, and attempts to reduce state-level siting authority in New York all failed to advance through the legislative process or did not receive final approval.

The final outcome of the 2026 legislative sessions strongly favored policies that support renewable energy development. A total of 29 siting-related bills were enacted across the country. Of these, 16 were classified as permissive, encouraging renewable energy deployment, while 12 made neutral procedural changes without significantly affecting project development. Only one enacted law was considered restrictive.

Several states introduced notable reforms. Virginia approved statewide solar siting standards and allowed battery storage systems co-located with solar projects to be developed by right in certain situations. Illinois strengthened its existing siting framework through a comprehensive energy package designed to improve project development processes. Oregon created temporary pathways to speed up permitting for clean energy projects, helping developers avoid lengthy state approval procedures. Washington adopted legislation supporting community benefit agreements while also limiting overly restrictive local ordinances that could delay renewable energy projects.

Utah became the only state to pass a restrictive measure during 2026. The law limits state incentives for solar projects developed on certain prime farmland. However, the final version of the legislation was considerably less restrictive than originally proposed.

Looking ahead, the Siting Solutions Project expects siting and permitting to remain a major legislative issue in 2027. Because many state legislatures begin each new session with a fresh legislative agenda, similar restrictive proposals are expected to return in states such as Oklahoma, Alabama, and Arizona. Meanwhile, states including Texas and Iowa are likely to become key battlegrounds where existing permitting systems are defended. At the same time, lawmakers in Pennsylvania, Virginia, and Indiana are expected to pursue new reforms that make renewable energy development easier while balancing local concerns with the growing need for reliable electricity generation. The report concludes that although efforts to block restrictive legislation proved successful in 2026, meeting future energy demand will require states to adopt even stronger policies that support clean energy deployment.
